Metrics Cannot Attach/Mount the Intended Storage
Issue
- Starting Metrics backup after work on the cluster and I get an error about storage:
<DATE_TIME> <DATE_TIME> 2 hawkular-cassandra-1-7voky Pod Warning FailedMount {kubelet test.example.com} Unable to mount volumes for pod "hawkular-cassandra-1-7voky_openshift-infra(96765ee3-8c28-11e6-916f-005056a6d599)": timeout expired waiting for volumes to attach/mount for pod "hawkular-cassandra-1-7voky"/"openshift-infra". list of unattached/unmounted volumes=[cassandra-data]

- Updating my cluster and metrics won't start back up
- Events indicate cassandra can't mount the volume
- Cassandra failing with error about permissions:
ERROR 20:01:35 Has no permission to create directory /cassandra_data/data
